The Van Allen radiation belt is a zone of energetic charged particles, ... in which region radiation levels vary. The belts are in the inner region of Earth's ...
The South Atlantic Anomaly (SAA) is an area where Earth's inner Van Allen radiation belt comes closest to Earth's surface, dipping down to an altitude of 200 kilometres (120 mi). This leads to an increased flux of energetic particles in this region and exposes orbiting satellites (including the ISS) to higher-than-usual levels of ionizing ...
The Van Allen radiation belts swell and shrink over time as part of a much larger space weather system driven by energy and material that erupt off the Sun's surface and fill the entire Solar System. Space weather is the source of aurora that shimmer in the night sky, but it also can disrupt satellites, cause power grid failures and disrupt GPS ...

This will expose them to higher levels of radiation than astronauts aboard the International Space Station. An artist's concept of the Van Allen belts with a cutaway section of the two giant ...
While some of the energetic beta particles followed the Earth's magnetic field and illuminated the sky, other high-energy electrons became trapped and formed radiation belts around the Earth. The added electrons increased the intensity of electrons within the natural inner Van Allen radiation belt by several orders of magnitude. [12]
SpaceX’s latest mission — a bold and risky trek into Earth’s Van Allen radiation belts by a four-person crew of civilians who will also aim to conduct the first commercial spacewalk — just ...
The belts are areas where concentrations of high-energy particles that come from the sun and interact with Earth’s atmosphere are trapped, creating two dangerous bands of radiation, according to ...
